Evaluation of blood type as a potential risk factor for hemorrhage during vaginal hysterectomy.

Objective: To examine the association between the O blood type and bleeding tendency in patient undergoing vaginal hysterectomy.

Methods: This was a retrospective cohort study including all women who had undergone vaginal hysterectomy at our institution between January 2015 and September 2020. All women underwent blood type and complete blood count testing pre- and post-operatively.

Evaluation of blood type as a potential risk factor for early postpartum hemorrhage.

Objective: Studies have demonstrated an association between ABO blood type and bleeding status. The aim of this analysis was to determine whether O blood type is associated with higher early postpartum hemorrhage (PPH) risk as compared to other blood types.

Study Design: In this retrospective case-control study, data was gathered form 4,516 deliveries occurring at our institution between 2014 and 2016.

Inhalation of a Short-Acting β2-Adrenoreceptor Agonist Induces a Hypercoagulable State in Healthy Subjects.

Background: Catecholamine infusion elicits an increase in clotting factors and this increase has been attributed to stimulation of β2-adrenorecptors (β2AR). Accordingly, we tested the hypothesis that inhalation of a short-acting selective β2AR agonist can induce a procoagulant state in healthy individuals.

Methods: We recruited 23 healthy volunteers (nine females; mean age: 26±0.
